The One With The Halloween Party

At Monica's Halloween party, Phoebe meets the friendly fiance (Oscar-nominated guest star Sean Penn, "Dead Man Walking") of her ditsy twin Ursula (also played by Lisa Kudrow) but becomes alarmed when she learns that her sister has misrepresented herself to her trusting future in-law. What's more, Phoebe finds herself attracted to him as well. Elsewhere at the shindig, Monica comes disguised as Catwoman and wonders if she could take down Phoebe's Supergirl character while Chandler arrives as a bunny and mistakes Ross' giant hybrid "Spud-nik" costume for something found on a sidewalk. In addition, Rachel runs out of candy and resorts to paying trick-or-treaters.
